what is the process to request for original divorce document form USCIS? How long it takes?
You can request original documents provided to USCIS. I have included a link below to the pertinent form. Be sure to thoroughly review the instructions. Also, my experience with getting originals back from USCIS is an extremely long wait (months/year). You may be able to get a certified divorce document from the pertinent family court not only faster, but at much less expense.
